The Next Project - Bringing our 84 Carrera back to life.

[clinerg]

Ahoy from George and Evie! We’re sailors and know too much about boats but not nearly enough about our car.

She’s a 1984 Carrera with some history…an old track car that was rejuvenated for street driving.
We’ve owned the car for quite a few years and she worked great until we went sailing.
After sitting in the garage for a few years, she no longer starts and has no spark.

Here’s what we’ve checked so far:

• 8/3/20205 - Replaced the DME Relay with one from Focus 9.
• 8/3/2025 - Speed Sensor reading ~1048 ohms. Voltage is >3 and seems to climb up to ~5 while cranking.
• 8/3/2025 - Crank Position Sensor reading ~360 to 440 ohms. Voltage seems the same as the Speed Sensor.

Any help on what to check next would be greatly appreciated. I hope to continue to post info about the issue as we keep researching/troubleshooting.

Here is the car:

Both sensors should be around 1000. Replace the low one. Maybe both, while you're in there. Does it have the updated two terminal head temp sensor?

I’m going to order both. Not sure about the head temp sensor. I will check and report back.

Thanks!

So I disconnected both sensors where they connect to the mounting bracket. The male end of the speed sensor just crumbled when I disconnected it. It’s the side that leads forward to the DME(?). I can’t find a part number for the portion that goes to the DME.
